The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hmm, I guess I don't have a wide enough screen to reproduce this. Is this a new bug in 99? You can use https://mozilla.github.io/mozregression/ to help test that easily.

I can confirm that the issue did not exist prior to version 99. Tested on 98.0a1 and can't replicate the same bug on the test page.

Okay thanks. Do you want to run a full bisection with mozregression to pinpoint what changeset caused this to start failing?
